title: [Development of morphological changes after experimental Mycobacterium avium infection in ducks and geese].
abstract: Ducks and geese were experimentally infected with the Mycobacterium avium. It was demonstrated that intramuscular and peroral infection causes morphological tuberculous changes. The first microscopically detectable changes induced by intramuscular infection occurred within 12 days. After 70 days from infection the affected organs were densely covered with tuberculous lesions. The development of microscopic changes is continuous and the development of affections is accompanied by an increase in the number of mycobacteria detectable in the sections. In ducks this trend is more pronounced than in geese. In both methods of infection liver and spleen are the first and the most frequent organs to be affected.
